摘要:
When being blended in a toner, a barium titanate external additive for toner enhances, in particular, the toner fluidity, electrical properties, and other relevant performance; concurrently achieves high image density and reduced background fog in a printer using the toner; and further reduces image defects, such as void, fading, and the like. An industrially advantageous producing method of the barium titanate external additive for toner is also provided. The external additive for toner of the present invention includes spherical barium titanate having a specific gravity of 5.6 g/ml or less.

An electrical plug connector comprises an insulating plastic base and a first and second series of elongate metal contact security respective opposite major faces of the base by an in-molding step so that respective back surfaces of the contacts and parts of their side surfaces are embedded in the plastic material while connecting surfaces are exposed for engagement with a complementary connector. During the in-molding process a cavity is formed between the two series of contacts at a rear end of the base by a mold member supporting rear ends of the contacts of respective series in spaced apart, parallel relation while front ends of the contacts are supported by attachment to respective carrier strips. A plug is force fitted into the cavity subsequent to molding supporting the rear ends of the contacts. Leading, front ends of the contacts have laterally extending anchoring portions and tapering, inwardly extending tips completely covered by the plastic material to ensure double securement to the base.

When being blended particularly in a color toner, a barium titanate external additive for toner enhances the toner fluidity, electrical properties, and other relevant performance; concurrently achieves high image density and reduced background fog in a color printer using the toner; and further retains high image quality even under a high-temperature high-humidity environment and a low-temperature low-humidity environment. An industrially advantageous producing method of the barium titanate external additive for toner is also provided. The external additive for toner of the present invention includes spherical barium titanate having undergone coating treatment with a hydrophobicizing agent.
摘要:
A liquid crystal display device which can prevent the generation of bubbles on an adhesive surface between a liquid crystal display panel and a face plate which protects the liquid crystal display panel is provided. In mounting the face plate on an upper polarizer of the liquid crystal display panel by way of an adhesive material, a picture frame is formed on a periphery of the face plate for enhancing design property. Although the picture frame is formed by printing black ink, a quantity of Si present in the black ink is set to not more than 0.7% and not less than 0.01% thus preventing the generation of bubbles attributed to defective adhesion between the face plate and the adhesive material.
摘要:
The semiconductor device includes a multilevel interconnection formed on a semiconductor substrate. The multilevel interconnection includes a plurality of wiring layers each of which is insulated by an insulating layer. A metal member is formed as a shielding film in a same plane as a wiring layer. As a result, the shielding layer can be formed without increasing the number of process steps.

A 3-electrode, surface-discharge type plasma display is capable of offsetting a radiation fields which is generated at the time of displaying, to reduce radiation noises. To drive the plasma display, an X-electrode and a Y-electrode are separated to an even number (2m) and an odd number (2m-1), respectively. During a resetting period and an addressing period, pulse voltage is applied to the even-numbered and odd-numbered electrodes at the same time, whereas in a sustained discharge period, the phase of the pulse voltage applied to the even-numbered electrode is delayed by 180 degrees from that applied to the odd-numbered electrode.
